600 Riverside County Vaccine Appointments Rescheduled Due To Weather-Related Shipment Delays Syndicated Local – CBS Los Angeles RIVERSIDE (CBSLA) — Severe weather across the country, which delayed vaccine shipments to California and shut down vaccination sites in Los Angeles and Orange counties, are also impacting the rollout in the Inland Empire and Ventura County. Orange County’s biggest vaccination site at Disneyland was abruptly shut down Thursday, and a clinic that just opened on Tuesday will have to close on Saturday due to the supply delays. The city of Los Angeles was also forced to postpone appointments for thousands of people because of supplies that were held up by winter storms across the country.
